Patent number: 8500943Abstract: A continuous composite fiberglass sucker rod for connection between a pump and a pump drive has a rectangular cross section. End fittings having a rod receiving cavity are connected to the rod ends using a curable adhesive. The rod fitting is maintained in a vertical position with the cavity facing upwardly. The rod end portion is positioned in the cavity with the end at the bottom of the cavity. Curable adhesive is introduced into the cavity. A centralizer bushing is used to maintain alignment of the rod relative to the cavity. A portable heating device receives the fitting and rod end portion and enhances the curing process.Type: GrantFiled: November 10, 2011Date of Patent: August 6, 2013Assignee: John Crane Production Solutions Inc.Inventor: Russell P. Rutledge, Sr.

Publication number: 20120141194Abstract: An end fitting for sucker rods or continuous sucker rods defines a rod receptacle with an interior surface defining void spaces having an axial radius of curvature of at least twenty inches. In one form, the fitting receptacle defines two such void spaces and the radius of curvature differs between them.Type: ApplicationFiled: February 10, 2012Publication date: June 7, 2012Applicant: Fiberod Inc.Inventors: Russell P. Rutledge, SR., Russell P. Rutledge, JR., Ryan B. Rutledge

Patent number: 8062463Abstract: An improved design and a method of assembly of end fittings to sucker rods which may be of conventional length or continuous sucker rods is described herein. The end fittings and rods are assembled so as to form wedges which enhance the connectability of the end fitting to the rod, and further, the wedge or wedges approach the rod asymptotically so as to avoid any abrupt discontinuities in the wedge or wedges thus substantially eliminating stress concentration areas and potential failure areas in the rod. The assembly method provides for integrity in the rod to end fitting assembly to promote longer connection life and fewer shop rejections and field failures.Type: GrantFiled: March 5, 2007Date of Patent: November 22, 2011Assignee: Fiberod, Inc.Inventors: Russell P. Rutledge, Sr., Russell P. Rutledge, Jr., Richard D. Burchett, Floyd L. Brownfield

Publication number: 20100288868Abstract: A coiling arrangement for a continuous composite sucker rod for a well sump includes a spool having a substantially cylindrical shape. A support structure rotatably supporting the spool about a rotation shaft, and for translatory movement. A guide arrangement moves the spool reciprocally such that the reciprocal motion of the support structure is along a direction that is parallel to the axis of rotation of the shaft. The rod is thereby accumulated on the spool in a spiral manner with minimal lateral deflection. In one form the spool is reciprocal relative to its support shaft. In another a support structure is reciprocal with the spool.Type: ApplicationFiled: May 13, 2010Publication date: November 18, 2010Applicant: Fiberod, Inc.Inventor: Russell P. Rutledge, SR.

Publication number: 20100239433Abstract: A continuous sucker rod preferably comprising fiberglass or composite material for use in an well is described herein. The continuous sucker rod may be connected at one end to a pump drive, via a polished rod, and at a second end to a downhole pump, via sinker bars or other weights. The continuous sucker rod preferably has at least two end fittings, one at each end of the continuous sucker rod. The end fittings, each having two ends and each being attached, at one end, to a respective end of the continuous sucker rod. The end fittings are preferably configured to enable connection to the polished rod and sinker bars respectively. The end fittings are connected to the continuous sucker rod so as to form wedges which enhance the connectability of the end fitting to the rod, and further, the wedge or wedges approach the rod asymptotically so as to avoid any abrupt discontinuities in the wedge or wedges thus substantially eliminating stress concentration areas and potential failure areas in the rod.Type: ApplicationFiled: June 4, 2010Publication date: September 23, 2010Inventor: Russell P. Rutledge, SR.
